Chef’s Secret
Never boil konbu when making dashi, as it can extract bitterness. Gently simmer below boiling point, and remove just as small bubbles form.
Substitutions
Best Match
Dried Shiitake Mushrooms
Varies
Excellent plant-based source of umami, though with a distinct earthy flavor profile.
Wakame Seaweed
1:1 (by weight, for broth)
Another edible seaweed, but less potent in umami and often used for texture in soups.
Nori (Roasted Seaweed)
Varies
While different texture, it provides a marine umami flavor, especially if rehydrated.
Mushroom Broth
1:1 (liquid)
A quick liquid substitute for umami in broths and soups.
Buying Guide
Purchase dried konbu from Asian markets. Look for thick, wide pieces with a whitish powder, which indicates high umami.
